[ 1 ] - مدل سازی پیامد انتشار کلر از مخزن ذخیره به کمک داده های میدانی
کلر و ترکیبات آن از مواد پرمصرف در صنعت می‌باشد و برای تولید طیف وسیعی از محصولات به وجود این ماده شیمیایی نیاز است. کلر عنصری است که در پوسته ی زمین و اقیانوس ها وجود دارد و یک ماده ی قوی و خورنده است. از این رو این ماده شیمیایی می تواند سبب ساز وقایع بسیار فاجعه باری گردد. در آمریکا، کلر پس از منواکسید کربن دومین ماده خطرناک از لحاظ میزان حادثه و جراحت می باشد. یکی از مهم ترین مطالعات میدانی ...
[ 2 ] - Removal of copper ions from aqueous solutions using polypyrrole and its nanocomposites
In this article, preparation of polypyrrole and its nanocomposites as adsorbents werediscussed and the capability of separation of copper ions from aqueous solution were studied.Polypyrrole was prepared by chemical oxidative polymerization method of pyrrole usingFeCl3 as an oxidant. The removal of Cu (II) was investigated using PPy, PPy/TiO2 andPPy/TiO2/DHSNa nanocomposites. The products were i...
[ 3 ] - Anionic/Non-ionic Surfactants in Aqueous Phase of Thin Film Composite Poly(Paraphenylene Terephthalamide) Nanofiltration Membranes
In this work, the Interfacial interfacial polymerization (IP) technique was employed using terephthaloyl chloride (TPC) and p-phenylenediamine (PPD), as reactant monomers, to prepare poly(paraphenylene terephthalamide) thin film composite (TFC) nanofiltration on polyethersulphone (PES) support layer. The effects of six different anionic and non-ionic surfactants, in the aqueous phase on the mor...
[ 4 ] - Studying Performance of Dubinin-astakhov and Dubinin-raduchkevic Equations to Evaluate Nanopore Volume and Pore Size of MCM-41 Particles (TECHNICAL NOTE)
MCM-41 particles were synthesized using inorganic raw materials and Cetyltrimethylammonium bromide (CTAB). The textural properties and structure of MCM-41 particles were characterized by XRD, SEM, TEM and N2 adsorption-desorption methods. To study performance of Dubinin-Astakhov and Dubinin-Raduchkevic isotherm models in evaluating mesopore volume and pore size of MCM-41 samples, the mesopore ...
